Utility model content
The utility model object is to provide a kind of novelty simple in structure, the bolt-type back seat backrest folding catch gear of good reliability.
For achieving the above object, the utility model provides a kind of bolt-type back seat backrest folding catch gear, its main points are: comprise mechanism rack and the swivel mount being rotationally connected with this mechanism rack inner side, before and after this swivel mount bottom, the described mechanism rack of both sides is respectively arranged with locating dowel pin and locking cap sliding tray, described locating dowel pin is close to described swivel mount, in described mechanism rack outside, be connected with swivel arm, this swivel arm middle part is arranged on described mechanism rack through lever swivel pin, described swivel arm one end is fixed with lock pin, described locking cap sliding tray is stretched out in described lock pin outer end, this lock pin external part sidewall is close to the sidewall of described swivel mount, on the described swivel mount between described lever swivel pin and lock pin, be provided with pull back spring, this pull back spring one end is fixed on the described mechanism rack of described swivel mount top, the other end is fixed on described swivel mount.Adopt above structure, while needing folding, because described swivel arm is provided with release lever away from one end of lock pin, upwards pull release lever, because swivel arm middle part is arranged on described mechanism rack through lever swivel pin, so swivel arm is around the rotation of lever swivel pin, thereby swivel arm is fixed with one end of lock pin, moves down, lock pin gets out of the way described swivel mount, folding that now can swivel mount; While not needing folding, swivel mount is dug, under the effect of pull back spring, be fixed with on swivel arm one end of lock pin and move, thereby drive on lock pin, move and prop up swivel mount, now, lock pin and locating dowel pin clamp swivel mount, realize locking.
As preferably: offer rotation hole on described mechanism rack, wear rotating bolt in this rotation hole, described swivel mount is solidly set on this rotating bolt, on the described rotating bolt in described swivel mount outside, nut is housed.So, above-mentioned rotating bolt, swivel mount and nut are fixed as one, therefore, simple in structure, rotate reliably, also easily realize the folding of swivel mount and locking.
As preferably: in the rotation hole of described mechanism rack, self lubrication bearing is housed, described rotating bolt is through this self lubrication bearing.Adopt above structure, due to the existence of self lubrication bearing, can greatly reduce the friction of rotating bolt, in the situation that guarantee good rotation, increase the service life.
As preferably: for the utility model for convenience detach, described rotating bolt is shoulder bolt.
As preferably: described nut is project-welding nut.
As preferably: described swivel mount one side has the arc-shaped limit groove coordinating with described locating dowel pin, opposite side has the deep-slotted chip breaker coordinating with described lock pin, so can realize the good fit of swivel mount and locating dowel pin, lock pin, failure-free is realized the folding of swivel mount and locking.
As preferably: the external part of described lock pin is equipped with locking cap.
, it is characterized in that: at least comprise 1 above-mentioned bolt-type back seat backrest folding catch gear, all fixedly backrest side pipe or backrest side stand on the swivel mount of this bolt-type back seat backrest folding catch gear.
The beneficial effects of the utility model are: 1) novelty simple in structure, can failure-free realizes folding and the locking of back of seat; 2) constituent elements does not arrange complicated processing stand, so handling ease and oad can access good assurance; 3), while using, rub little, so noise is little.
